BARREL-VALVE.

Specicaton of Letters Patent.

Patented Oct. 26, 1909.

Application led November 13, 1908. Serial No.462,399.

To all whom t't may concern:

Be it known that I, CHARLES F. TERNEY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Im: provement in Barrel-Valves, of which thefollowing is a specification.

This invention relates to a valve or bung for tapping beer or otherliquids from a barrel by air pressure;

The object of this invention is to produce a valve of this characterwhich is simple and inexpensive in construction and reliable inoperation, which will securely close the barrel when the tapping rod orpipe is wit-hdrawn therefrom and which can be readily dismembered andassembled for cleaning or repairing.

In the accompanying drawings consisting of 2 sheets: Figure 1 is avertical longitudinal section of my improved valve in connection with atap showing the parts in the position which they occupy when the valveis opened and the tapping rod is pushed into the barrel. Fig. 2 is avertical transverse section at right angles to Fig. 1 and taken on line2-2 in that figure. Fig. 3 is a vertical section showing the bushing inthe same position as that indicated in Fig. 1 but the tap, plug andconnecting parts turned into a position corresponding to Fig. 2, whichposition the parts occupy when the valve is closed. Fig. 4 is a bottomplan view of the tap. Fig. 5 is a top plan view of the bushing and thehead of the plug, the latter being in the position which it occupieswhen the valve is closed and the tap is removed therefrom. Fig. 6 is aview similar to Fig. 5 with the head of the plug removed. Fig. 7 is athe plug. Fig. 8 is a vertical longitudinal section of the bushing withthe plug and connecting parts removed therefrom.

Similar letters of reference indicate corresponding parts throughout theseveral views.

A represents the bushing of the valve or bung which is preferably ofcircular form and provided on its periphery with a screw thread awhereby the same is secured within an opening in the head of the barreland also provided at its inner or front end with a head B having a portor opening b on one side of its center. On the outer or rear side of thehead around its port the same is raised slightly, forming a valve seatb1, as shown in Figs. 1, 3 and 8.

bottom plan view of the head of l/Vithin the front part of the bore ofthe bushing the same is provided with an internal screw thread c whichpreferably trends toward the left and within the outer or rear part ofits bore the bushing is provided on diametrically opposite sides withtightening ribs d, d the front or inner sides @Z1 of which are inclined,as shown in Fig. 8. The ribs d are arranged outside or beyond thediameter of the screw thread c of the bushing.

E represents the plug whereby the port in the head ofthe bushing isopened and closed. The plug is provided with an external screw thread ewhich engages with the internal screw thread of the bushing.

In one part of the screw plug at the side of its center the same isprovided with an opening f which is arranged parallel to the axisthereof and on another part of the screw plug at the side of its centerthe same is provided with a stopper or gate Gr. Upon turning the screwplug toward the right the same is moved axially -outward or away fromthe head ofthe bushing by the screw connection between these parts andthe opening in the plug is brought into alinement with the port of thebushing head, while upon turning the screw plug toward the left the samewill move axially inward toward the head. of the bushing and the stopperis caused to engage with the seat around the outer end of the port Z)and close the same. Owing to the screw thread connection between theplug and the bushing, the stopper engages with the valve seat onlyduring the last part of the turning movement of the plug toward theleft, and upon turning the screw plug toward the right the stopperrecedes from the valve seat during the rst part of this movement,thereby enabling the valve to be operated very easily andl avoidingundue wear on the same.

The stopper may be constructed of rubber or any other suitable materialand secured to the plug in various ways. As shown in the drawings, thesame is constructed in the form of a flat plate which is provided on itsouter or rear lside with a dove tail po-rtion g which engages with acorrespondingly formed seat h extending radially inward from theperiphery of the plug on the front side thereof, as shown in Figs. 1,2,' 8 and 6. In order to prevent the stopper fromA being engaged withthe valve seat with undue pressure upon closing thevalve, ythe front orinner side of the plug is provided with a stop or projection z' which isadapted to engage with a bearing surface or seat l on the rear side ofthe bushing head adjacent to its port, as shown in Fig. 3.

J represents a head or cover plate secured to the outer end of the plugand provided on diametrically opposite sides of its periphery withlaterally projecting or peripheral lugs y', j which are adapted toengage wit-h the ribs Z of the bushing for preventing the plug frombeing removed from the bushing. The plug head is provided on one side ofits center with an opening jl which is in line with the opening f of theplug. On its front side the plug head is provided with forwardly orinwardly projecting lugs K, K which engage with notches or seats Z, Z atthe rear end of the plug, thereby interlocking the plug and its head andcompelling the same to turn together. The bushing and its head aresecured against displacement relatively to each other in the directionof the axes of the same by means of screws m passing through the headfrom the outer side thereof and entering threaded openings in the rearend of the plug. In assembling the parts, the plug is first screwed inthe bushing until its outer or rear end is separated a suitable distancefrom the front side of the ribs of the bushing. The diameter of thecoperating threads of the bushi` and plug is less than the diameter atthe inner edge or bore of the ribs of the bushing. After the screw plughas been thus introduced in the bushing, the plug head is passed axiallyinto the bushing while the lugs of the head are in alinement with thespaces between the opposing end of the ribs of the bushing and then theplug head is interlocked with the plug by engaging its front lugs withthe recesses of the plug and is secured to the latter by means of thescrews m. After the plug head has been thus applied to the plug thelatter cannot be fully unscrewed from the bushing, inasmuch as theperipheral lugs y', y' of its head will strike the internal ribs CZ ofthe bushing.

N represents the tubular body of the tap which is arranged eccentricallyon the rear or outer side of a coupling head O and which is providedwith a laterally projecting nozzle p. The body of the tap is adapted toreceive the tapping tube or pipe Q whereby the liquid is to be withdrawnfrom the barrel and the nozzle is adapted to receive a tube or conduitthrough which compressed air is delivered into the barrel for forcing orexpelling the liquid therein through the tapping rod. The coupling headO is provided on its front side with a tubular shank r which is adaptedto enter the outer or rear end of the bushing and around this bushingthe coupling head is provided on its front side with a packing ring r1of rubber or other suitable material which is adapted to engage with theouter end of the bushing and form a tight joint between the same and thecoupling head while the tapping device is in operation.

Means are provided for compelling the tap to turn with the plug foropening and closing the valve and also detachably connecting the samewith the bushing. The preferred means for this purpose as shown in thedrawings consist of a pair of seats or recesses s, 8 formed within thebore of the shank r and adapted to receive outwardly projecting lugs s1,s1 formed on the outer side of the plug head and two coupling lugs t, tprojecting laterally from diametrically opposite sides of the peripheryof the shank and adapted to cooperate with the tightening ribs CZ of thebushing. In attaching the tap to the plug and bushing, the tap is firstplaced with its laterally projecting lugs t, t in alinenient with thespaces between the ribs CZ of the bushing and then moved forwardly sothat its shank enters the outer end of the bushing and its laterallyprojecting lugs t, t pass through the spaces between the ribs and itsrecesses s, s receive the coupling lugs s1, s1 of the plug head. Afterthe tap has been thus applied to the bushing and plug it is turnedtoward the right, thereby causing the laterally projecting lugs t, t ofthe shank to engage with the inclined front sides of the ribs Z of thebushing and cause the head of the tap and the packing r1 to be drawnfirmly against the outer end of the bushing, thereby forming a tightconnection between these parts. l/Vhile thus turning' the tap forconnecting the same with the bushing, the plug is also turned by meansof the interlocking lugs and recesses s, s1, thereby causing the stopperof the plug to be moved away from the port of the bushing head and theopening of the plug and plug head to be brought in alinement with theport of the bushing head. In the coupled position of the tap and plug,the body of the tap is in line with the openings of the plug and plughead, so that when the valve is opened, the port of the bushing head,the openings of the plug and plug` head, and the tubular body of the tapare all in alinement.

Before turning the tap for opening the valve, the tapping pipe or rod Qis pushed part way through the stuiiing box g at the outer end of thetap and after the latter has been fully turned toward'the right togetherwith a plug, the tapping rod is pushed inwardly through the openings ofthe plug and plug head, the port of thebushing and into the barrel forwithdrawing the liquid therefrom.

Vhen disconnecting the tapping device from the barrel, the tapping rodis first withdrawn from the barrel and into the body of the tap and thenthe latter is turned toward the left until the tightening lugs on itsshank are disengaged from the inclined inner sides of thc bushing ribsand brought into alinement with the spaces between the same. Thereafterthe tap may be withdrawn axially from the bushing and the plug head.Vhile thus turning the tap toward the lett for disengaging the same fromthe plug, the latter is also turnedkin the same direction for bringingits stopper over the valve seat of the bushing and closing the valve.

It will be noted that in the act of attaching the coupling` to thebushing the valve will be opened and that these parts can not be againuncoupled until the valve has been closed.
